AUTOMATIC STATION INDICATOR FOR TRAINS.

Application filed June 16,

This invention relates generally to signaling devices and has more particular reference to a novel train station indicating device.

The invention hasfor an object the provision of a train station indicating device, which will indicate the station at which the train is and also at which station the train will stop next, and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention and of the objects and advantages there of, reference will be had to thefollowing description and accompanying drawing, and to the appended claims in which the various novel features ofthe invention are more particularly set forth.

Referring to the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a side elevational view of a portion of a train having the invention applied thereto.

Fig. 2 is a fragmentary vertical sectional view, taken on the line 22 of Fig. 1.

Fig. 3 is a fragmentary vertical sectional view, taken on the line 33 of Fig. 2.

Fig. 4 is a horizontal sectional view, taken on the line 4-4 of Fig. 3.

Fig. 5 is an enlarged fragmentary portion of Fig. 4, certain parts being shown in section.

Fig. 6 is a fragmentary vertical sectional view, taken on the line 66 of Fig. 3.

The reference numerals 10 indicate generally, cars of a train, and preferably at the centers of each of the cars and near the ceiling thereof adjacent to fixed advertising boards 10 casings 11 are secured. These casings 11 are each formed with windows 12 and positioned behind these windows are spring actuated rollers 13. These rollers have springs 14 secured at one of their ends to the rollers, and at the other ends to shafts 15, fixedly held to the side of the casing 11 by-brackets 16.

Shafts 18 are rotatively mounted in the casing 11 and rollers 19 are fixed on these shafts. Strips of material 20 are wound onto the rollers 13 and the rollers 19, and these strips are provided with indicating means, such as 21 printed or otherwise formed thereon and advertising matter such as 20. The shafts 18 are formed with a pair of toothed portions 22v and ratchet wheels 23 with central toothed apertures are engaged on one of the toothed portions 22. Adjacent these ratchet wheels are gears 24 provided with spring pressed pawls 26 engaging the 1927. Serial No. 199,175.

ratchet wheels 23. Adjacent the gears 24 are other ratchet wheels, 27 with central toothed apertures engageable with the other toothed portions 22 which are positioned just next to these ratchet wheels. Spring pressed pawls 28 attached to the gears 24 engage these ratchet wheels 27. The ratchet wheels 23 and pawls 26 act in the opposite direction to ratchet wheels 27 and pawls 28. A solenoid 29 provided with an arm 30 is capable upon being energized of pushing members 23,24, and 27 so as to slide along the shafts 18 so that the central toothed apertures of ratchet wheels27 engage the toothed portions 22, and the central toothed apertures of ratchet wheels 23 disengage the toothed portions of shaft 18. Solenoids 31 provided with arms 32 are capable, upon being energized, of pushing members 23, 24, and 27 back into their first mentioned positions. Resilient'means such as springs, 45 act between the arms 32 and wheels 27 and arms 30 and wheels 23 to keep the members 23,24, and 27 in close relation.

Solenoids 33 have their movable'cores connected with racks 34 meshing with gears 24. The racks 34 are urged downwardly by springs 35 connected between the bottoms of the racks and casing 11. The casing 11 has stamped therefrom a tongue 36, having roughened portions 38 and elliptically shaped members 39 with similar roughened portions, which are positioned on the sides of the tongue 36, and held by a bolt 40. Projections 41 from the racks 34 engage against the edges of the members 39, limiting the possible downward movement of the racks. The edges of the members 39 are formed with deep knurling 42 so that the projections may act upon a gripping surface.

The operation of the device consists in manually closing a switch for a short period of time, just as the train enters a station to energize solenoids 33, causing the cores thereof to move the racks 34 upwardly against the action of springs 35, and then to allow the springs to move the rack downwardly. The moving racks rotate gears 24, and this rotation is transmitted to turn shafts 18 in one direction or the other, according to whether rack wheels 23 or 27 engage the roughened portions 22. The spring actuated drums l3 normally act to wind the material 20 upon itself, and the drums 19 on shafts 18 are turned as ust explained, to either allow the material to wind upon the drums 13 or from the drums.

The passengers on the train may l'ookt'hrough the windows 12 at the indicating means 21 on the material Which moves the correct amount to properly indicate. A switch may be manually closed to operate solenoid 31 and another switch to operate solenoid 29, so that.

will be understood that the device is, nevertheless, susceptible of considerable modification therein, and I therefore reserve the privilege of resorting to all such changes as may be fairly embodied Within the spirit and sco eof'the invention as claimed. 7

aving thus described my invention, What I claim" as new and d'esire-tosecure by United States Letters Patent is 1., In an automatic station indicator for trains, the combination with a solenoid actuated' rack connected with web advancing rolls, of a casing housing the said indicator, a tongue projecting therefrom, and having a roughened portion, an elliptically shaped member bolted to the tongue, and having a similar roughened portion engaged against the first roughened: portion, the edges of the elliptically shaped member being provided with. knurli-ngs, and a projection from the said rack engageable against the knurled edge of the elliptical member to limit the travel of the rack, and the movement of: the Webv roll, as determined by the position of the elli-ptically shaped member.

2; In an automatic station indicator for trains, the combination with a solenoid actuated rack connected With Web advancing rolls, of a casing housing the said indicator, a tongue projecting therefrom, an elliptically shaped member bolted to the tongue, the edges of the elliptieally shaped member being provided- With knurlings, and a projection trom the said rack engageable against the knurled edge of the elliptical member to limit the travel of the rack, and the movement ofthe Web roll, as determined by the position of theelliptically shaped member.

In testimony whereof I have affixed my signature.
